How to drop multiple tables with common prefix in one query?

Problem: Suppose we have a situation where we need to drop those tables that have some prefixes string, so it is possible to drop those tables with a common prefix in a single query.

Solution: yes it is possible to drop all those tables that have the common prefix in a single query. Using following query you can delete all those tables that begin with a certain prefix string. In where condition just put the common prefix string in where condition (Like ‘prefix%’)

DECLARE @query NVARCHAR(MAX) = N'';

SELECT @query += '
DROP TABLE '
    + QUOTENAME(s.name)
    + '.' + QUOTENAME(t.name) + ';'
    FROM sys.tables AS t
    INNER JOIN sys.schemas AS s
    ON t.[schema_id] = s.[schema_id]
    WHERE t.name LIKE 'MX_100%';

EXEC sp_executesql @query;

This query may create an issue, if a table has a foreign key relationship, you'll either need to drop them first or arrange the output to drop the tables in a certain order.
If you want to monitor exactly what goes on when the query is running then use the following query. 

DECLARE @query varchar(4000)
DECLARE csr CURSOR FOR
SELECT 'drop table [' + Table_Name + ']'
FROM INFORMATION_SCHEMA.TABLES
WHERE Table_Name LIKE '<prefix>%'

OPEN csr
WHILE 1 = 1
BEGIN
    FETCH csr INTO @query
    IF @@fetch_status != 0 BREAK
    EXEC@query)
END
CLOSE csr;
DEALLOCATE csr


Note: If you are not a Database developer then don’t use above query contact to your database department.

Remove special character from string in MongoDB

Problem: Suppose wehave a collection and one field is type string contains some special character (like !@#$%) and we don’t want these special character.

What is difference between UNION and UNION ALL in SQL Server

We use UNION and UNION ALL operator to combine multiple results set into one result set.
UNION operator is used to combining multiple results set into one result set but removes any duplicate rows. Basically, UNION is used to performing a DISTINCT operation across all columns in the result set. UNION operator has the extra overhead of removing duplicate rows and sorting result.
UNION ALL operator use to combine multiple results set into one result set but it does not remove any duplicate result. Actually, this does not remove duplicate rows so it is faster than the UNION operator. If you want to combine multiple results and without duplicate records then use UNION otherwise UNION ALL is better.
Following some rules for using UNION/UNION ALL operator
1.The number of the column should be the same in the query's when you want to combine them. 2.The column should be of the same data type. 3.ORDER BY clause can be applied to the overall result set not within each result set.
4.Column name of …
